Easy fix. Buy an Aimpoint PRO on February 29th. Turn it on and leave it on. The next February 29th (4 years later) replace the battery and drive on. Aimpoint PRO has a 5.7 year battery life (50,000 hours). If that is not enough battery life, go to an Aimpoint Comp M4 which will go 100,000 hours.
It's a thought ... maybe when I recover from the tax bill this year I'll look around a bit.
